Battle of Cunaxa

In September 401 BCE, approximately 90 stadia north of Babylon at a place Xenophon names Cunaxa, the army of Cyrus the Younger met Artaxerxes II's larger force in pitched battle. The Greek phalanx on Cyrus's right wing routed the Persian left under Tissaphernes with little resistance, but Cyrus, leading a cavalry charge against his brother's center, wounded Artaxerxes before being killed by a javelin to the face. The Greek hoplites returned from their pursuit to find Cyrus dead and the Persian army still in possession of the field. They had won their part of the battle and lost the war.
